HAND-TORCH.

Specification of Letters Patent.

Patented July 12, 1921.

Application filed April 12, 1920. Serial No. 373,161.

To all to 710m it may concern:

Be it known that I, Mourns VoLKns citizen of Russia, residing at Brooklyn, listings county, New York State, have invented certain new and useful Improvements in Hand- Torches, of which the following is a specification.

This invention relates to hand torches that are adapted to receive a supply of gas and discharge the same as a jet of flame and the object of the same is to provide gas with as little oxygen as possible to afford a flame so that little heat is given off and the flame will have little destructive ellect when directed upon. paper, paint, varnish or fabric.

These and other objects and details of the invention are more fully described in the following specification, set forth in the appended claims and illustrated in accompanying drawings, wherein:

Figure 1 is a side view of the torch in operation,

Fig. 2 is a longitudinal sectional view,

Fig. 3 is a cross sectional view.

The Bunsen burner provides abundant means for supplying oxygen and mixing the same with illuminating gas to burn in the flame, but for the purpose which the present invention is adapted, it is desirable to limit the supply of oxygen to a minimum.

The device shown in the drawings consists of a body portion comprising a ring 5, through which runs the pipe 6, having a pocket 7, in which the air and gas are mixed and to which are connected the inlet pipe 8 and the nozzle 9. The inlet pipe consists of the nipple to which a flexible pipe may be attached, and a valve 10, that normally obstructs the inlet, but which is opened by the lever 11, fulcriuned in lugs 12 on the outside of the ring 5. The lower end of the valve 10, carries the spring 13, and the confining nut 14, which holds the valve in its closing position across the inlet and it will be seen in Fig. 1, that the lever 11, is partly concentric with the ring 5, and when-the device is grasped by the hand of the operator, a pressure exerted on the lever will open the valve without interfering with the grasp of the hand.

As the gas passes through the pockets 7, from the inlet to the nozzle a certain amount of air is carried outward by the blast, but this amount is limited on account of the limited ingress for more air and to further limit the mixture of oxygen a lid 15, is hinged to the rear of the pipe 6, and over the pocket 7, and the same has a lip 16, at its free end and is located beneath the finger of the hand that holds the torch. This lid is held open by the spring 17, that bears against the extension 18, and air is admitted to the pocket but if too much enters the pres sure of the linger on the lip 16, will close the lid and the air and gas mixture is decreased.

The inner end of the inlet pipe has the reduced orifice 19, to reduce the gas blast to a small and line jet which is projected through the pocket 7 and the nozzle 9, to be burned at the outlet of the latter. Durmg the passage of the blast through the pocket, it takes with it as much air as the operator will permit by allowing the lid to open.

It will thus be seen that the device is compactly arranged to be held in the hand of the operator and that the gas supply and the air supply are within the immediate control of the said hand, leaving the other hand of the operator free to handle the material to be singed or treated, but it is obvious that the parts may be otherwise-arranged or modified without departing from the essential features above described or from the scope of the appended claims.

hat I claim as new is 1. In a torch, the combination of a connecting pipe having an inlet and an outlet and an intermediate pocket, a spring actuated cover to the pocket and adapted to re main normally open, and a spring pressed control valve adapted to close the inlet pipe; both cover and valve adapted to be operated singly or simultaneously by the hand that holds the torch.

2. In a torch, the combination 01"- a bowl and ring adapted to be grasped in the hand and the bowl having an inlet pipe and an outlet nozzle, a valve in the inlet pipe, a le ver iulcrumed on the ring and adapted to be operated by the grasping hand to open the valve, a hinged cover for the bowl adapted to be closed by the grasping hand, and a spring at the rear end of the cover and adapted to normally open the same.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses, this 26th day of ll larch, 1920.
